HomeWeb Front-endJS Tutorial自动刷新网页,自动刷新当前页面,JS调用_javascript技巧

reload 方法,该方法强迫浏览器刷新当前页面。
语法:location.reload([bForceGet])                                                                                                                           参数: bForceGet, 可选参数, 默认为 false,从客户端缓存里取当前页。true, 则以 GET 方式,从服务端取最新的页面, 相当于客户端点击 F5("刷新")

replace 方法,该方法通过指定URL替换当前缓存在历史里(客户端)的项目,因此当使用replace方法之后,你不能通过“前进”和“后退”来访问已经被替换的URL。
语法: location.replace(URL)  

在实际应用的时候,重新刷新页面的时候,我们通常使用: location.reload() 或者是 history.go(0) 来做。因为这种做法就像是客户端点F5刷新页面,所以页面的method="post"的时候,会出现"网页过期"的提示。那是因为Session的安全保护机制。可以想到: 当调用 location.reload() 方法的时候, aspx页面此时在服务端内存里已经存在, 因此必定是 IsPostback 的。如果有这种应用: 我们需要重新加载该页面,也就是说我们期望页面能够在服务端重新被创建, 我们期望是 Not IsPostback 的。这里,location.replace() 就可以完成此任务。被replace的页面每次都在服务端重新生成。

你可以这么写: location.replace(location.href);

返回并刷新页面:

复制代码 代码如下:

location.replace(document.referrer);
document.referrer //前一个页面的URL


不要用 history.go(-1),或 history.back();来返回并刷新页面,这两种方法不会刷新页面。

附:
Javascript刷新页面的几种方法:

复制代码 代码如下:

    history.go(0)
    location.reload()
    location=location
    location.assign(location)
    document.execCommand('Refresh')
    window.navigate(location)
    location.replace(location)
    document.URL=location.href


自动刷新页面的方法:
1.页面自动刷新:把如下代码加入区域中

其中20指每隔20秒刷新一次页面.

2.页面自动跳转:把如下代码加入

区域中

其中20指隔20秒后跳转到http://www.jb51.net页面

3.页面自动刷新js版

复制代码 代码如下:



JS刷新框架的脚本语句

//如何刷新包含该框架的页面用 

复制代码 代码如下:

 
//子窗口刷新父窗口

( 或 刷新   )

//如何刷新另一个框架的页面用 


如果想关闭窗口时刷新或者想开窗时刷新的话,在中调用以下语句即可。
复制代码 代码如下:

开窗时刷新
关闭时刷新

Understanding the JavaScript Engine: Implementation DetailsUnderstanding the JavaScript Engine: Implementation DetailsApr 17, 2025 am 12:05 AM

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.

Python vs. JavaScript: The Learning Curve and Ease of UsePython vs. JavaScript: The Learning Curve and Ease of UseApr 16, 2025 am 12:12 AM

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

Python vs. JavaScript: Community, Libraries, and ResourcesPython vs. JavaScript: Community, Libraries, and ResourcesApr 15, 2025 am 12:16 AM

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

From C/C   to JavaScript: How It All WorksFrom C/C to JavaScript: How It All WorksApr 14, 2025 am 12:05 AM

The shift from C/C to JavaScript requires adapting to dynamic typing, garbage collection and asynchronous programming. 1) C/C is a statically typed language that requires manual memory management, while JavaScript is dynamically typed and garbage collection is automatically processed. 2) C/C needs to be compiled into machine code, while JavaScript is an interpreted language. 3) JavaScript introduces concepts such as closures, prototype chains and Promise, which enhances flexibility and asynchronous programming capabilities.

JavaScript Engines: Comparing ImplementationsJavaScript Engines: Comparing ImplementationsApr 13, 2025 am 12:05 AM

Different JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.

Beyond the Browser: JavaScript in the Real WorldBeyond the Browser: JavaScript in the Real WorldApr 12, 2025 am 12:06 AM

JavaScript's applications in the real world include server-side programming, mobile application development and Internet of Things control: 1. Server-side programming is realized through Node.js, suitable for high concurrent request processing. 2. Mobile application development is carried out through ReactNative and supports cross-platform deployment. 3. Used for IoT device control through Johnny-Five library, suitable for hardware interaction.
